| Summary: | A new method of processing the liquid crystal color change data obtained from transient heat transfer experiments is presented. The approach uses the full intensity history recorded during an experiment to obtain an accurate measurement of the surface heat transfer coefficient at selected pixels. Results are presented for a model of a turbine blade cooling passage with combined ribs and film cooling holes. The implementation of the technique and the advantages to be gained from its application are discussed. |
